[0001] The utility model relates to the technical field of concrete mixing equipment, in particular to a steam heating pipeline for a batching machine. Background Art

[0002] With the continuous progress of society and the rapid development of science and technology, the construction industry has entered a new era of vigorous development. As a key branch of the construction industry, the concrete mixing industry has also ushered in unprecedented development opportunities. Whether it is high-rise buildings, bridges and tunnels, or roads and residential communities, the concrete mixing industry plays a vital role in providing a solid material foundation for modern urban construction.

[0003] In many areas, due to cold climate conditions, mixing plants face a common problem: difficulty in unloading aggregates. This is mainly because the low temperature causes the water in the aggregates to freeze, making the aggregates hard and difficult to flow, thus affecting the normal production process. This problem is particularly prominent in winter, bringing many inconveniences and challenges to the daily operation of mixing plants.

[0004] Based on this, the utility model designs a steam heating pipeline of a batching machine to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a steam heating pipeline for a batching machine to solve the problems raised in the above background technology.

[0008] Preferably, the rear end of the connecting pipe is fixedly connected to the corresponding transfer pipe, the front end of the connecting pipe is not sealed and opens downward, the end of the dispersion pipe away from the connecting pipe is not sealed and opens downward, and the left end of the steam pipeline is sealed.

[0009] Preferably, two components of hoppers are symmetrically arranged at the bottom of the batching hopper, and the material carrying assembly is arranged at the intersection of the tops of the two components of hoppers.

[0010] Preferably, the two dispersion pipes in the material carrying assembly correspond to the two component hoppers respectively.

[0011] Preferably, the side walls of the two groups of the distribution hoppers on the opposite side are connected to a driving assembly, and the bottom ends of the distribution hoppers are movably connected to baffles, which are transmission-connected to the corresponding driving assemblies.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0013] 1. The utility model solves the problem of aggregate freezing under low temperature conditions by arranging a material carrying component and a pipeline component to cooperate with each other and using steam heating. The steam heating pipeline is used to fully heat the aggregate in the batching hopper.

[0014] 2. The utility model installs the connecting pipe and the dispersion pipe at the bottom of the supporting angle steel by arranging the supporting angle steel, thereby preventing the impact of the aggregate discharge on the connecting pipe and the dispersion pipe, thereby extending the service life of the pipeline components, the connecting pipe and the dispersion pipe.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1 - Figure 4 Example 1 is described. The figure shows a steam heating pipeline for a batching machine, comprising a support frame 1, a batching hopper 2, a material supporting assembly 3 and a pipeline assembly 4. Three groups of batching hoppers 2 are fixedly connected to the support frame 1 at equal intervals. The inner cavities of the three groups of batching hoppers 2 are all fixedly installed with material supporting assemblies 3. The rear side of the support frame 1 is fixedly installed with a pipeline assembly 4. The pipeline assembly 4 includes a steam pipeline 401, a transfer pipe 402 and an air inlet flange 403. The steam pipeline 401 is fixedly installed on the rear side of the support frame 1. Three groups of transfer pipes 402 are connected to the steam pipeline 401 at equal intervals. The three groups of transfer pipes 402 correspond to the three groups of batching hoppers 2 and extend through the batching hoppers 2. The right end of the steam pipeline 401 is fixedly connected to the air inlet flange 403.

[0025] See also Figure 4 and Figure 5 The three groups of material carrying components 3 shown in the figure include a material carrying angle steel 301, a connecting pipe 302 and a dispersion pipe 303. The material carrying angle steel 301 is fixedly connected to the middle of the inner cavity of the batching hopper 2. The bottom of the material carrying angle steel 301 is fixedly connected to the connecting pipe 302. There are two dispersion pipes 303 symmetrically arranged, and both dispersion pipes 303 are connected to the connecting pipe 302.

[0026] In this embodiment, the steam pipeline 401 is connected to the steam source through the air inlet flange 403. The steam enters the transfer pipe 402 through the steam pipeline 401, and is then evenly distributed in the batching hopper 2 through the transfer pipe 402 and the dispersion pipe 303. Since the oblique ends of the connecting pipe 302 and the dispersion pipe 303 are facing downward, the steam can heat the aggregate more effectively while preventing heat loss. In addition, the setting of the supporting angle steel 301 can protect the steam pipeline 401, the connecting pipe 302 and the dispersion pipe 303 from direct impact when the aggregate falls, thereby extending the service life of the pipeline assembly 4, the connecting pipe 302 and the dispersion pipe 303.

[0027] It should be noted that using the pipeline assembly 4 to heat the aggregate can effectively prevent the water in the aggregate from freezing, thereby ensuring the fluidity of the aggregate and ensuring the smooth production process of the mixing station. The mixing station can maintain the fluidity of the aggregate under cold climate conditions, thereby ensuring the continuity and stability of concrete mixing, which not only improves production efficiency but also reduces the operational risks caused by changes in climate conditions.

[0028] Example 2

[0029] See also Figure 1 and Figure 5 Example 2 is described. This embodiment further illustrates Example 1. In the figure, the rear end of the connecting pipe 302 is fixedly connected to the corresponding transfer pipe 402. The front end of the connecting pipe 302 is not sealed and opens downward. The end of the dispersion pipe 303 away from the connecting pipe 302 is not sealed and opens downward. The left end of the steam pipeline 401 is sealed.

[0030] Furthermore, two component hoppers 5 are symmetrically arranged at the bottom of the batching hopper 2, and the material carrying assembly 3 is arranged at the intersection of the tops of the two component hoppers 5;

[0031] Furthermore, the two dispersion pipes 303 in the material carrying assembly 3 correspond to the two component hoppers 5 respectively;

[0032] In this embodiment, the front end of the connecting pipe 302 is not sealed and the opening faces downward, the end of the dispersion pipe 303 away from the connecting pipe 302 is not sealed and the opening faces downward, and the openings of the connecting pipe 302 and the dispersion pipe 303 are forty-five degrees oblique, so that the steam can be more evenly distributed when entering the batching hopper 2, thereby improving the heating efficiency. At the same time, due to the design of the oblique opening, the steam will form a certain diffusion angle when entering the batching hopper 2, which helps to reduce the loss of heat during the transfer process and ensure that the aggregate can be fully and evenly heated.

[0033] It should be noted that the steam is dispersed into the dispersion pipes 303 on both sides through the connecting pipe 302, and is dispersed into the corresponding distribution hopper 5 through the downwardly opening inclined opening of the dispersion pipe 303, so that the aggregate in the distribution hopper 5 can be fully and evenly heated.

[0034] Example 3

[0035] See also Figure 1 and Figure 6 Example 3 is described. This embodiment further illustrates Example 2. In the figure, the side walls of the two component hoppers 5 on opposite sides are connected to a drive assembly 6. The bottom end of the hopper 5 is movably connected to a baffle 7, which is transmission-connected to the corresponding drive assembly 6.

[0036] In this embodiment, the distribution hoppers 5 are symmetrically arranged at the bottom of the batching hopper 2, so that the aggregate can be evenly distributed to each distribution hopper 5. The driving component 6 is used to drive the baffle 7 to pull it up, so that it can adjust its position as needed, and adjust the opening size of the discharge port at the bottom of the distribution hopper 5, thereby controlling the discharge speed and amount of the aggregate.

[0037] It should be noted that the drive assembly 6 can adopt a cylinder, an electric motor or other drive devices to adapt to different working environments and requirements. The movable connection mode of the baffle 7 can be sliding, rotating or other appropriate connection modes to ensure that the baffle 7 can flexibly adjust its position to achieve the purpose of accurately controlling the discharge of aggregates. Through the coordinated use of the drive assembly 6 and the baffle 7, the speed and amount of aggregate discharge can be accurately controlled, thereby meeting the requirements of different mixing processes for aggregate ratios.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
